三、防护措施
已开启windows自动更新的系统会自动安装补丁，无需手动更新升级。未开启自动更新的计算机及所有windows服务器按照以下方法做好防护。
1.安装补丁
目前，微软官方已针对支持的系统版本发布了修复该漏洞的安全补丁，官方补丁下载地址：。
由于网络问题、计算机环境问题等原因，windows update的补丁更新可能出现失败。用户在安装补丁后，应及时检查补丁是否成功更新。
右键点击windows图标，选择“设置”，选择“更新和安全”-“windows更新”，查看该页面上的提示信息，也可点击“查看更新历史记录”查看历史更新情况。
针对未成功安装的更新，可点击更新名称跳转到微软官方下载页面，建议用户点击该页面上的链接，转到“microsoft更新目录”网站下载独立程序包并安装。
2.临时应对措施
若无法成功安装补丁，则可通过禁用print spooler服务来进行缓解：
（1）单击windows图标或搜索框，搜索“services.msc”，在服务应用中找到print spooler服务。
（2）双击“print spooler”，停止运行服务，同时将“启动类型”修改为“禁用”。
